Mitt Romney asserts tax rate over 13%
Cites a decade of returns, but offers no proof
Republican presidential candidate Mitt Romney said Thursday that he has paid a tax rate of at least 13 percent in each of the past 10 years, offering his fullest explanation to date of his tax status. ‘‘I did go back and look at my taxes and over the past 10 years I never paid less than 13 percent. I think the most recent year is 13.6 or something like that. So I paid taxes every single year,’’ he told reporters. Democrats have hit Romney repeatedly on the issue, using it as an illustration for their argument that the Republican presidential candidate’s tax policies would favor the wealthy, like himself, over the middle class.
